摘要： PURPOSE:To evaluate regenerating function in a raw water treating apparatus, by measuring the variation with time of conductivity of the discharged liquid from a regenerating and backwashing process of an ion exchange resin. CONSTITUTION:When the ion exchange resin received in a tank 2 is saturated, a change-over valve 7 is changed over to carry out a regenerating and backwashing process but conductivity of a discharged liquid obtained by passing through a liquid through the resin 1 is detected in timewise change by a conductivity meter 13. By this method, it can be detected easily and positively whether the regenerated resin in the regenerating and backwashing process has sufficient regenerated function or not and, therefore, errors or troubles can be prevented.

摘要： PURPOSE:To regenerate ion exchange resins with good efficiency by passing a sulfuric acid used for regeneration of the cation exchange resin through the strong basic anion exchange resin, and regenerating the same with a sodium hydroxide soln. CONSTITUTION:At the time of regenerating ion exchange resins, the cation exchange resin is regenerated with a sulfuric acid soln., and the whole or part of this waste liquid of regeneration is contacted with the strong basic anion exchange resin. Then, the Cl form of the strong basic anion exchange resin once assumes CO3 form or SO4 form. Thereafter, this anion exchange resin is regenerated with a sodium hydroxide soln. If the resins are regenerated in this way, the efficiency of regeneration is excellent and the amount of regenerating agents can be less.

摘要： PURPOSE: To regenerate efficiently a titled ion-exchange resin by passing a liq. to be treated by using an ion-exchange resin using an OH-type granular anion-exchange resin and an H-type cation-exchange resin as the ion exchange resin.
CONSTITUTION: A granular anion-exchange resin or a granular cation-exchange resin is treated with a liq. chemical having ion selectivity equivalent to or higher than that of the ion to be removed in a liq. to be treated. Then the liq. to be treated is passed by using an ion-exchange resin using an OH-type granular anion-exchange resin or an H-type granular cation-exchange resin as the exchange resin to regenerate the ion-exchange resin. The granular anion (cation)-exchange resin, wherein an basic group such as a quaternary ammonium group and an amine group or an acidic group such as a sulfonic group, an carboxyl group, etc., is introduced into the constitution as the exchange group, is used in this method.

摘要： PURPOSE: To reduce high-electric conductive liquid waste, by reserving it in liquid waste tanks annexed to columns for regenerating both of cation and anion- exchange resins, and using it for the regeneration of said ion-exchange resin.
CONSTITUTION: Liquid waste tanks 32, 33 for high-electric conductive liquid waste are annexed to a cation-exchange resin regenerating columns 3 and an anion-exchange resin regenerating column 4. In the regenerators connected to a column 1 for the desalination of condensed water, low-electric conductive liquid waste is reserved in a liquid waste tank 2 directly connected to the desalinator column 1, while high-electric conductive liquid waste is reserved in the liquid waste tanks 32, 33 directly connected to the regenerator columns 3, 4 and used for the regeneration of ion-exchange resins. Thus, an amount of water to be used is saved.

摘要： PURPOSE:To raise the recovery efficiency of valuables and reduce greatly the recovery cost by treating diluted solution of the valuables discharged from ion exchange resin regeneration process by means of an ultrafiltration membrane, etc. CONSTITUTION:A diluted solution of valuables discharged from sweetening-off and sweetening-in processes, among the regenerated waste water of ion exchange resin, is introduced into the tank 2 through the pipe 1, passed through the valve 3, the pump 6, the filter 7, and the pressure pump 8, treated by the ultrafiltration membrane or reverse osmotic membrane separator 4, and then stored in the tank 14 for filtrate and in the tank 9 for concentrate. When the concentrate does not reach a given concentration, it is circulated to the separator 4, and also when a given conentration is reached, it is recovered in the storage tank 9 through the storing pump 20. Also, the filtrate of the tank 14 is sent by the pump 21 to a necessary place to utilize it as regenerated water. Thus, valuables, which have been discarded hitherto, are recovered with consumption of less energy, incidental facilities are made smaller, and the recovering cost is reduced.

摘要： PURPOSE:To perform stable regeneration free from regeneration specks within a short time with a relatively small amount of regenerating liquid by circulating and passing the regenerating liquid through the used ion exchange materials outside the ion exhange material packed tower then regenerating. CONSTITUTION:Regenerating liquid of a tank 2 is passed through the ion exchange materials whose specified ions have attained permissible concentration by supplying the same to an ion exchange material packed tower 1 through pipes 15 and 13 and circulating the same to the tank 2 through pipes 12, 16 and 17. At this time, the concentrations at which the ions to be removed can coexist are kept at 1/2 or under, preferably 1/5 or under in the ions eluted in the regenerating liquid/regenerated ions so that the specified ion concentration in the regenerating liquid does not increase. Then, the space velocity in a column for the ion exchange materials of the regenerating solution may be increased, the regeneration reaction progressed nearly simultaneously and the regeneration free from regenerating specks by the less regenerating liquid accomplished.
